receiving a message comprising an authentication challenge and determining a characteristic of said message,
calculating an authentication response based on said authentication challenge, an authentication input parameter and an authentication algorithm,
said method being characterised by the steps of:
retrieving one authentication input parameter from a number of input parameters stored on said information storage means or one authentication algorithm from a number of algorithms stored on said information storage means in response to said characteristic; and

responding to said authentication challenge by using said retrieved authentication input parameter or algorithm
